G4+ Storm ECU

G4+ Storm ECU
The Link G4+ Storm delivers performance that rivals any engine management system on the market. This ECU is more than capable of running sequential injection, ignition and variable valve timing on most of today's engines. The black Storm offers all of the advanced G4+ tuning features at an extremely competitive price. 8 x injection & ignition, 8 x analog & digital inputs.

Requires "A" & "B" Looms


The G4+ Storm offers the latest in high end aftermarket engine management. You will be stunned by the G4+'s performance, features and reliability.

Designed and built to be the best, the Storm delivers the results, with more functions than normally demanded by both tuner and driver:


  • Eight saturated injection drives, eight ignition outputs, eight analog volt inputs, eight digital inputs, eight auxiliary outputs*
